(iii) The average number of trees above 7 feet in girth per compartment 
is 618. As some compartments contain between 1,500 and 2,000 
such trees it is impossible to prescribe equal annual girdlings 
without making sub-compartments. The annual girdlings pre- 
scribed in the following table must therefore be abandoned if it is 
found necessary to girdle and extract equal numbers each year. 
The sub-periodical yield must, of course, be rigidly adhered to. It 
is quite possible that, owing to the variations in the number of 
logs that can be extracted from year to year, no objections will be 
found to this annual scheme.
